Serial No. seems a '1 Claims. 8-18) Qur invention relates to a novel method of pulling or contracting fabric or cloth made from Vinyon. or'from Vinyon combined with other fibers, which may be of vegetable, animal or synthetic origin. 1 For example, fibers of cotton, silk, wool, or other material can be combined individually or in any desired combination with the Vinyon. The Vinyon alone or combined with other fibers maybe in the form of a yarn or thread, .woven, knitted, or braided to form a.

cordance with the contour of the finished articles which is to be made. Steam, under its normal pressure from a boiler, is now sprayedagainst the exposed surface of the fabric, passes through the fabric against the backing member, which deflects the steam against the surface of thefabric next to the backing member. The width of the steam spray is preferably the width of the fabric and travels across the exposed area of the cloth.

If the fabric is to be dyed, it is subjected to a dyeing operation before being subjected to the steam operation. The dye which we have advantageously employed is made of one-half toluol and one-half alcohol, with any desired color of pigment. To this we add two percent of acetone as a solvent, and two per centof ox gall .to facilitate penetration. The proportions given are illustrative and not restrictive. The goods are dipped in or sprayed withthe dye. They are then stretched on a board or-form and subjected to the action of steam in the manner .hereinbefore described. After the steaming operation, the fabric is dipped in or sprayed witha resin solution, such as for example, Rohfiex, which gives a surface finish and seals the-dye 'in the material.

Among the many articles which can be made from the finished fabric are hats, shoes, hand bags, pocketbooks, brief cases, and back-grounds for pictures, paintings, for needlework and tapestry. By this method the fabricis stiffened without the use of size, glue or similar materials.

While we havefound that the best and most uniformresults are obtained with steam, good results can be obtained with water heated above is in stretched condition and the backing member is preferably employed. The hot water can be applied by a dipping or spraying operation.

The action of steam fuses and sets the fabric whereby it is stiffened, and thereafter it does not contract from its stretched condition.

Having thus described our invention, whatwe claim as new'and desire to secure by Letters Patent is: g

1. The method of treating Vinyon fabric which consists in supporting the fabric in a stretched condition to expose one face thereof, subjecting the exposed face to the action of steam and the opposite face to the action of the steam which has passed through the fabric and been deflected against such opposite face of the fabric,

whereby the fabric is fused and set to obtain a stiffened fabric in substantially'unretracted con dition.

2. The method of treating fabric made of subjecting the exposed side to steam which passes through the fabric and deflecting such steam against the opposite face of the fabric, whereby the fabric is'fused and set to obtain a stiffened fabric in substantially unretracted condition.

3. The method of treating fabric containing Vinyon, which consists in stretching the fabric on a board with marginal portions fixed at short distances to the board, and directing steam against the exposed face of the fabric and over the entire area of suchexposed face, wherebythe fabric is fused and set to obtain a stiffened fabric in substantially unretracted condition.

4. The method of treating fabric containing Vinyon," which consists in coloring the fabric,

thereafter securing it in stretched condition on a backing member to expose one surface of the fabric, passing steam to said exposed surface to pass through the fabric, and deflecting such steam after it has passed through the fabric back againstth opposite faceof the fabric, whereby a colored, fused fabric is obtained.

5. The method of treating fabric containing.

Vinyon, which consists in coloring the fabric, thereafter supporting it in a stretched condition, thereby exposing one surface thereof, passing steam to said exposed surface to pass through the fabric, deflecting the steam after it has passed through the fabric against the opposite face of the fabric, and then subjecting the'fabric to the F when not water is to be used t fabric action of a resin solution to surfaceflnish the expose one face thereof, passing steam to said exposed face to pass through the fabric, defiecting such steam after passing through the fabric against the opposite face of the fabric, and applying a surface finish to the fabric, whereby a colored, fused fabric is obtained.

'7. The method of treating fabric containing Vinyon, which consists in subjecting the fabric while in a stretched condition and fixed at marginal portions on a'supporting surface to the ac- 1 5 tion of water heated to a temperature above 190 F., whereby the fabric is fused and set to obtain a stiffened fabric in substantially unretracted condition.
